2 Claims. (Cl. 25613.1)

This invention is an improved traic guard particularly intended forroads or streets carry'- ing fast moving traflic.

One of the objects is to prevent a vehicle from traveling into dangerousterritory, this to be effec'ted without unduly damaging the vehicle orcausing injury to its occupants. Other objects may be inferred.

' Referring to the accompanying drawings:

Figure 1 is a side elevation of the new traffic guard.

Figure 2 is a top plan. Figures 3 and 4 are side and end elevations,respectively, of details shown by the right-hand portion of Figures land 2.

Figures 5 and 6 are top and side elevations, respectively, of detailsshown by the left-hand.,

end portion of Figures 1 and 2, Figure 5 being partially cross-sectionaland taken from the line V-V of the latter figure.

Figures 7 through 10 are cross-sections of modifcations of theinvention.

Figure 1l is a cross-section of the invention when used as a trafficseparator.

Figure 12 is a top plan of Figure 1'1.

More particularly, fence posts I are spaced along the side of a road.These posts mount parallel, vertically spaced, steel cables 2 which aretautened in the usual manner.` Preferably, the posts are spaced somewhatfarther apart than is usual and are relatively strong.

Laterally spaced brackets 3 are xed to the cables 2 and right angularlyproject from them toward the traffic. The brackets may be made of heavysteel strips bent ir V-form and may have their ends-fixed to the cablesby U-bolts 4.

A guard rail4 5 is mounted by the central parts of the brackets 3 so asto be parallel to the cables 2. This guard rail may consist of one ormore lengths of steel strip which are mounted by the brackets in a.vertical plane and are joined in overlapped relationship, as at 6, withthe end edges of the upper strips pointing in the direction of thetrailics movement. It is obvious thatsuch a guard rail is flexible.

Each end of the guard rail is held against longitudinal displacement bya spring element. This Il)a screwed onto it. 'I'hen the end of the guardrail may be provided with a bolt I I which passes through a slot I2 inthe spring element and is provided with a nut IIB. This last functionsas a lock.

Braces 3 may be used between the ends of the brackets 3, if desired.

The fence posts I may be made from rolled steel sections providing acentral at web Ia from which angular flanges Ih extend. The flanges IIJmay have apertures I through which U-bolts I3 are passed for the purposeof mounting the cables 2. In the case of "each end post, these U-boltsI3 may also serve to mount the plate 8, and auxiliary U-bolts I4 may beused to further x the cables 2 to this plate.

The operation of vthe ltraffic guard described is rather obvious. Incase an automobile leaves the road it will strike the guard rail 5 andglide along it without striking the posts I. 'Ihe overlapped connections6 being such that no proj jections oppose the automobile, no unduedamage will occur at these points. The entire assembly is flexible andthere is little chance of the stresses being concentrated at any one ofthe I I5. Also, the braces 3 shown by the preceeding ,y

figures are eliminated. l Figures 8, 9 and 10, respectively, show theguard rail or member as consisting of a cable I6 clamped to the brackets3 by U-bolts l, two parallel cables I6* clamped to'the brackets 3 byT-members 42, and a ilattened cable Iiib clamped to the brackets bybroad U-bolts 4b. l

" Figures l1 and 12 show a construction like that first described,except that the posts I8L are made of wood and the guard rail assemblyis used in duplicate so as to separate two oppositely moving lines oftramcs We claim:

1. A tralilc guard Aincluding the combination of a post,'a spring-steelstrip -bent in the form of a goose-neck and having oneend mounted on *YY said post, and a guard rail mounted by theother end of saidspring-'steel strip and extending horizontally away from said post, saidstrip' and guard rail being interconnected by adjustable means wherebythe tension applied to the latter by the former-may be varied. l

2. A tramo guard including the combination of a post, a spring-steelstrip bent in the form of a goose-neck and having one end mounted onsaid post, and a guard rail mounted by the 5 other end of saidspring-steel strip and extending horizontally away from said post, rightangular brackets being oppositely xed to said strip and said guard railand provided with an interconnecting screw fastening, and said strip andsaid guard rail having overlapping portions which are adjustably boltedflatly together.
